I was looking at a specific date earlier in the week (today I think) and noticed SYD-MEL fares on QF, cheapest available was $860 one way (as an aside when did it come that expensive?). But on same SYD-MEL flights you could do SYD-MEL-SIN for $690 or thereabouts. Do people ever hidden city ticket? I guess in this instance one could have done via CBR for half the price, or even less on ZL via ABX!
